VApplication led January' l16, 19,28. Serial No. 247,046.

Figure -1 is a view in front elevation oi the `improved machine.

Figure2 is a view 1n elevationv ofthe machine taken Jfrom the right of Fig-v ure1. fr y TheV machine ingeneral comprises a receiving table orplatform 4for the cartons which are manually .placed thereon." The moving of the cartons in such position onV such platform actuatesy a trigger which 1n.

turn engages a clutch withL theoperating mechanism. Movement of the. operating mechanism firstv functions to supply a suitmoistened gummed tape f across the top side of the carton and then to lift the carton upwardly into a chute which is provided with `brushes vertically .disposed at yits diametrically opposite sidesfor sticking the ends ofthe moistened tape down against the sides ot the `cartons, andL yholdingsuch tape kin position until the gummed `material thereon sets. also provided for suitably discharging the onto a trackway.

In the construction shown 'in the draw ings, a supporting framework is provided y comprising a pairof side frames r1 and 2,

connected vby suitable crossm'embers 3 to. l K

f anism mayL be'used. Asthetape passes vided with a gear pinion. 9 which meshes witha gear wheel 10. The gear 10 is'in'ter.

mittently connected to a main shait'11` by n, clutch 1,2 of suitable standard construc- Means arev The chute tionhwhichv maintains such'connection Lfor one revolution only, of the shaft.

The clutch 12 is caused to function so as pivotally mounted at 17 tol side frame2.

The upper end of the arm 16 has a trigger 18 rigidlyfastened thereto,'the upper. end

.19 Y. of which is in position to vbe engaged vand rocked to the'right, as viewed in Figure 2, by la carton 2O when said carton ismanually moved into position on receiving'platviorm 21.

Engagement of the clutch 12 rotates 11 upon which is keyed .various operating elements., The'irst yoperation to take place upon theqrotation ofthe shaft 11 is for vthe vpurpose .ot supplyingl moistened gummed tape across the top of thek cartons placed in the machine. This lis accomplished by acam to connect the gear 10 to shattll `by a rod 13 pivoted to oney arm ofthe bell crank 1.4. The'other arm of the bell crank 14 is connected by ak link 15 to al rocker armv 16 wheel 22, `keyed on shaft` 11y which actuates va roller 23 mounted on the middle portion o f a link 24. The lower end of link 2.4 is pivotally mounted on .a bearing stud 25,

rigidlyv mounted in a bracket 26 which with y the vbearing member 27 helps to support shaft 11'. The'upper end oflink 24is bi-f vfurcated and pivotally pinned to one end of a link 28 which has its other end pivoted tothe medial portion ot a link 29. lThe lower end of link 29 is pivotally connected to an arm '30` Vwhich in turn is pivotally mounted insupporting framework. -The upper end of link 29 rests on a carriage 31 which'is slidably mounted on aninclinedk chute 32. n K,

v supports a gummed .tape strip 33 which is supplied-from a roll 34 in box` 3,5, The carriage 31 Jfor feeding tape 33 is of standard construction and the detailsv are.V notessentialwto this invention as any standard form of tape-feeding-mechdown'the chute 3,2, it passes` overfan `up- `standing brush 36 mounted ina receptacle 37 l adapted to contain fa supply of waterment of the tape-feeding mechanism is yarf ranged to supply a lengtliof moistened tape which extends across the top of the carton, as shown in Figure 1, and projects a suitable distance from the opposite sidethereof.

The next movement in sequence of operation is to sever the length of moistened tape at the same time that the receiving platform lifts the carton upwardly. Movement upwardly of the receiving platform 21 is accomplished by a crank arm 39, keyed to shaft 11 at one end,`having its other end pivotally connected to the lower end of a pitinan 40. The upperend of pitman 4() provided with a slot 41 which embraces a bearing stud or pin 42 secured' to a collar 43 that is rigidly mounted on a vertical table liftingshaft 44.

"A bearing 45, formed in the end of a rigid Y arm v46, carried on side trames 2, is provided for holding the lower end of the shaft 44 in vertical position 1n conjunction with the Vupper end of the shaft which is rigidly mounted on the vunder side of the receiving and lifting table 21. rlhe ripper end of shaft 44,- underneath table 21, also carries a crosshead 47, rigidly mounted thereon, the ends of which ride in guideways 48 and 49 for guiding the table 2l in a vertical direction when lifted upwardly. The slot 41 in the upper end of vpitman 40permits the table and carton supported thereon to remain sta- `tionary during the operation of `the tapefeeding mechanism, so that lupward move-` ment thereof is not commenced until after a suitable length of tape has been fed into position over the top or the carton.

The collar 43 is provided. with a lug or projection 50 which engages the end of an arm 51 pivotally mounted on a shaft 52. T he shaft 52 carries a sleeve 59 which has an The outer end of arm 53 is pivotally connected to the lower end of a link rod 54, the upper end of which-is pivotally connected at 55 to one Aend ot' a tape-severing knife56. The opposite end of the tape-severing knife 56 is piv otally mounted at 57 to the framework. r-lhis mechanism is so timed and arranged that the knife 56 will sever the moistened gummed tape at about the same time that the cartonV has been raised to a horizontal level with the severing knife.

The continued upward movement of the shaft 44 on receiving' platform 21 carries the carton 2O upwardlyinto a chute 60 in which is supported a pair of diametrically-opposed, vertically positioned brushes 61 and 62. These brushes contact with the carton at the points where the' strip 'of tape lays there-- acr thus brushing down the endsl of the tape snugly against the sides of the carton and sealing said tape securely thereto. Movement of the table is sufficient to raise the carton so that the lower edge thereof passes by an inwardly-turned shoulder 63 formed on a spring arm 64 carried by the chute. The shoulder 63, engaging under the bottom of the raised carton, prevents the return of said carton when thel supporting land comprise an a'rin 66 rigidly mounted horizontally on the top end of the verticallydisposed rocker arnr67. The lower end of arm 67 is bolted or otherwise suitably secured to a casting 68, oivotally mounted on a stud 69, rigidly secured to side frame 2. To keep the upper end of arm 67 in proper alinement with the top end of the chute 60, a guide 70 isslidably mounted thereon which rides in a guideway 7l mounted on the chute 60. f

Means for actuating the arm 67 comprise a cam wheel 72 keyed to shaft 11 which carries a roller on one face thereof for contacting with and lifting the outer end of an arm 74, the inner end of which is keyed to a shaft 75, journaled on the side frames 1 and 2. `Shaft 75 protrudes beyond the side' frame'2 and has keyed thereon an upstanding arm 76, the arm 74, shaft 75, and arm' 7 6 thus forming a bell-crank. The upper end of the arm 76 is pivotally'connectedto one end of a link77, the other end of which is pivotally connected to the rocker arm 67.

A suitable trough or chute 7 8 is attached to the upper end of the cylindrical chute 60 for receiving the carton 20 when moved by the arm 66.

In theoperation of this machine the cartons are suppliedY thereto by any suitable means, such as an endless belt conveyor, and

are manually placed in position on the rc-V the arm 16,` link 15, bell-crank 14 and rod 13 to the clutch 12, causing'the clutch to connect the driven shaft`11. j

Initial movement of the .main shaft 11 causes the cam 22 to rock the link 24to the right as shown in Figure 1. Such ymovement of the link 24 carries link 28 `and lever 29Y to the right, and thus draws the carriage 31 down the inclined guideway i2-to the position shown in full lines in Figure 1. Such movement of the' carriage 51 feeds a suitable strip or length of' moistened gummed tape acrossthe top of the carton 20, so as to project a suitable distance from the opposite side thereof.

' During this movement of the machine, the

gear 10 to the main iipper end of the pitman 40. By'the time tape has been fed into position across the' top of the carton, pin 4 2 has reached the bottom of slot 41 and continued movement of the ycrank 39 causes the pitman` 4()v to raise the shaft 44. Then the shaft/14 and table 21 have been raised a short distance, preferably to bring the top kof the "carton-20 onra hori- Zontal plane with the 'tape-severing knife Y 56,'the lug 5() engages the arm 51 and raises said arm upwardly, thus rocking the arm 53 downwardly. The downward movement of arm 53 shifts the rod 54, the upperend ofA which. isfconnected at 55 to knife 56, also downwardly, causing 'the knife 56 to sever the length of moistened'tape. f l Continued upward movement of the shaft 44 and table 21 brings the carton 20 into engagement Awith the brushes 61 and 62, said brushes being mounted so as tojwipe' the vprotruding ends of the gummedtape down against the opposite sides rof the carton 20 and thus seal the tape securely thereto.v lVhen the table 21 has reachedfits upward limitof motion, the carton 20f'has'been'lifted a suflicient height toperinit the shoulder 63 of spring arm 64 to snap underneath lthe bottom side of the carton and retain it in suoli lifted position when the table 21 recedes to its original receiving position.

During the return ofthe table 2,1 to its initial position, the roller 73 on disk wheel 72 engages the outer end of the arm 74 and rocks the end of said arm upwardly. Such movement of the arm 74 rocks the shaft 7 5 and arm 76 in a bell-crank motion, causing the upper lend of arm 7 6 torock to the right as viewed in Figure 1. The link77 which connects the upper end of arm 76 to the rocker arm 67 draws said rocker arm tothe right, as viewed in -Figure 1, thus causing thewhorizoiital arni 66 to push the upstanding carton,`which has been raised above the top end'of chute 60, overonto the chute or conveyorway 78.
